What's changing

Say what you will about Jerry Jones, but the Dallas Cowboys owner didn't lie when he promised it would get "very uncomfortable" at Valley Ranch after a second straight 8-8 season. Rob Ryan was sent packing as defensive coordinator and replaced by 72-year-old Monte Kiffin, who will switch the Cowboys to a 4-3 scheme. Offensive coordinator Bill Callahan likely will inherit play-calling duties from coach Jason Garrett, who might still be in denial. Running backs coach Skip Peete was fired and replaced by Gary Brown.

» RB Felix Jones: A former first-round pick, Jones had a shot at Dallas redemption when DeMarco Murray went down for six games with a foot injury. Jones (playing on two bad knees) couldn't fill the void, one reason why the Cowboys set a franchise low for rushing yards in a 16-game season.

With the offseason officially under way, Around the League will examine what's next for all 32 teams.

» CB Mike Jenkins: The additions of Brandon Carr and Morris Claiborne put Jenkins in limbo last season, and a slow recovery from shoulder surgery didn't help. He worked in the slot after Orlando Scandrick went down, making little impact. He's expected to look for a starting job on the open market.

What they need

The Cowboys are overdue for a makeover along their offensive line. It was a problem all season, and quarterback Tony Romo's mobility is the only thing that kept this unit from total embarrassment. Tyron Smith is a good fit at left tackle, but upgrades should be sought elsewhere. If Jones has run out of chances, the Cowboys would be wise to find a capable backup for Murray, a supremely talented but seemingly injury-prone starter. The Cowboys must protect themselves at strong safety, where Barry Church is attempting to come back from a torn Achilles tendon.

Offseason crystal ball

The Cowboys open the offseason $20 million over the cap and needed to restructure contracts with several players to get under. With that in mind, don't expect a big fish to land in Big D. Improving the offensive and defensive line likely will be a focus during the NFL Draft. With Romo turning 33 before Week 1, don't be surprised if the Cowboys draft a developmental quarterback in the mid-to-late rounds.
